Sakamoto Days

Once feared as the greatest hitman in the world, Taro Sakamoto walked away from the assassin life after falling in love with Aoi, a convenience store clerk. He married her, started a family, and settled into a quiet life running a neighborhood convenience store, eventually gaining considerable weight along the way. But when a bounty is placed on his head, Sakamoto's peaceful retirement comes to an end as assassins from his past begin coming after him and his family.
